Can you spot the Spring Triangle?

As the Northern Hemisphere enters spring, a triangle of stars rises in the east, made up of bright beacons from three prominent constellations.

The illustration shows the sun in the center, and Earth passing between Saturn and the sun.

What is an opposition?

Opposition marks the middle of the best time of year to see a planet … but why?

What is a conjunction?

When you hear the word “conjunction” in astronomy, you know it means 2 objects close together on our sky’s dome. This post defines inferior and superior conjunctions, plus discusses conjunctions between planets, stars and the moon.

The blue ball of Earth orbits the yellow sun, and a line extending along the plane made by their mutual orbit is drawn outward toward a starry background.

Word of the week: Ecliptic

The ecliptic is the path the sun takes across our sky. It’s the Earth-sun plane, and, more or less, the plane of our solar system. Stargazing tip: Learn the whereabouts of the ecliptic in your sky. You’ll always find the sun, moon and planets on or near it.
